Abstract
Abstract The sound of the swing of a golf club is sensed and actuates a circuit to randomly select one of a plurality of visually distinctive indicia, such as different colored LEDs or flags, for a fraction of a second. One set of indicia is located on the ground proximate the ball. In order to observe and identify the selected indicia, the golfer must keep his head down and steady during the swing. A second set of identical indicia may be provided for use by an instructor. The second set of indicia may be located remotely from the first.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
An instructional device for improving the golf swing comprising means for sensing the sound of a golf club striking a ball, means for generating an actuation pulse in response to the sensing of the sound of the ball being struck, means for generating a series of clock pulses in response to said actuation pulse, selection means having a plurality of outputs and an input, said input being operably connected to receive said clock pulses, said selection means randomly selecting one of said plurality of outputs, in response to said clock pulses, a first plurality of visually distinctive energizable indicia, means for receiving said actuation pulse and for operably connecting said indicia with said random selection means to energize one of the said indicia associated with the randomly selected output for the duration of said actuation pulse.
Claim 2
Dependent Claim
136 words
An instructional device for improving the golf swing comprising means for sensing the sound of a golf club striking a ball, means for generating an actuation pulse in response to the sensing of the sound of the ball being struck, means for generating a series of clock pulses in response to said actuation pulse, selection means having a plurality of outputs and an input, said input being operably connected to receive said clock pulses, said selection means randomly selecting one of said plurality of outputs, in response to said clock pulses, a first plurality of visually distinctive energizable indicia, means for receiving said actuation pulse and for operably connecting said indicia with said random selection means to energize one of the said indicia associated with the randomly selected output for the duration of said actuation pulse.
Claim 3
Dependent Claim
28 words
The device of claim 1 wherein said actuation signal generating means comprises amplifier means for generating said actuation pulse in response to the output of said sensing means.
Claim 4
Dependent Claim
16 words
The device of claim 2 wherein said actuation signal generating means comprises sensitivity adjusting control means.
Claim 5
Dependent Claim
32 words
The device of claim 2 wherein said actuation signal generating means further comprises means for generating said actuation signal for a given time period after receiving the output of said amplifier means.
Claim 6
Dependent Claim
12 words
The device of claim 1 wherein said indicia comprise light generating means.
Claim 7
Dependent Claim
14 words
The device of claim 5 wherein said light generating means comprise light emitting diodes.
Claim 8
Dependent Claim
16 words
The device of claim 1 wherein said indicia comprise means for generating light of different colors.
Claim 9
Dependent Claim
62 words
The device of claim 1 further comprising a second plurality of visually distinctive energizable indicia remotely and physically located from said first plurality of indicia, means for energizing one of said indicia from said second plurality of indicia to correspond with the selected indicia from said first plurality of indicia, whereby the second plurality of indicia are easily viewable by an instructor.
